LagomorphShipping (Japanese: ピカミミPikaMimi) is the belief in a romantic relationship between Ash's Pikachu and Dawn's Buneary. It is a considered rival of KrazyShipping. The name originates from Lagomorpha, the order that rabbits and pikas, Buneary and Pikachu's real-world counterparts, belong to. This is one-sided canon on Buneary's side, whose crush on Pikachu was a running feature in the Diamond and Pearl series; Pikachu has yet to reciprocate.

Buneary develops a crush after seeing Pikachu save a potato. At one point, she grabs Pikachu and starts dancing with him, causing Pikachu to yell and Buneary to cry. When Dawn asks Buneary if she wants to come along with them, Brock says, "You can spend time with Pikachu." Ash finishes with saying, "Looks like she'll like that."

Ash and Dawn have a Double Battle in Contest style, with Pikachu and Aipom versus Buizel and Buneary. However, Buneary's first instinct is to flirt with Pikachu, striking a pose and winking at him, until Dawn states, "This is an appeal battle, not a date."

Buneary is walking away from Happiny to try to go through the maze by herself. Pikachu runs up to her and grabs her hand to try to get her to stop. This makes Buneary so happy that she hugs Pikachu and the three proceed to walk together, all the while the two hold hands together and Happiny being piggy-backed by Pikachu with Buneary comforting Happiny while she is being lulled to sleep, giving them the impression of being a small family.

When hiding in the elevator and looking outside for Rotom, Buneary hides with Ash and Pikachu on the left, despite Piplup and Dawn hiding on the right side of the elevator. Also, when telling Brock about Rotom, once again, Buneary hides behind Pikachu.

Buneary appears a bit shy around Pikachu after reuniting with him in Undella Town. He spots her hiding behind Mamoswine's leg and calls out to her happily. This gives Buneary back her nerve and she snuggles up to Pikachu with him appearing happy as well.

After Buneary and Buizel used Ice Beam and Water Gun respectively to let Ash, Dawn, and others to cross the stairs of the Space-Time Towers, and Pikachu thanked Buneary, Buneary pulled up her fur to hide her blushing away from Pikachu.

At the end of the theme, Pikachu points to the up arrow, Croagunk points to the right arrow, Piplup points to the down arrow, and Buneary points to the right arrow, respectively. Each arrow reveals a different image, and in the image on the right, Buneary is snuggling with Pikachu and she has hearts for eyes. She is also seen winking in a flirtatious manner.

Many supporters of this shipping use it as evidence of PearlShipping (Ash and Dawn), in a similar fashion to how people use VineShipping as evidence of AdvanceShipping; Professor Oak once stated that the feelings of a Trainer are reflected by their Pokémon. As such, if two Pokémon fall in love, the Trainers will too. However, if Dawn has a crush on Ash, she is to date being a lot more subtle about it than Buneary is about her feelings for Pikachu. Some will also point out that Buneary had a crush on Pikachu before Dawn caught her.
